The core-removing machine for the hard core of the rubber hose has the beneficial effects: the use is convenient, safe and reliable; the rubber hose is subjected to continuous core-removing; the production efficiency is increased; the potential safety hazard is eliminated; and the space occupied by production is smaller.
Description
Technical field
The invention belongs to the flexible pipe production equipment, relate to the hard core mandrel string of a kind of rubber hose.
Background technology
Skeleton strengthens the interior punch die that uses in the flexible pipe production process, plastic material is arranged usually, quality of rubber materials and steel matter, use steel matter as the production technology of interior punch die hard core method flexible pipe production technology, this technique uses the steel wire rope of hoist engine that hard core is pulled out from body at present, the length that will equal at least hard core in production process hoist engine and body distance could realize that hard core deviates from entirely, in case the large fracture of steel wire rope elasticity can cause major accident, depoling is gone and must be isolated when therefore producing, produce space hold very large, and back and forth folding and unfolding production efficiency of skeleton rope is very low.
Summary of the invention
The present invention provides a kind of rubber hose esy to use, safe and reliable hard core mandrel string in order to remedy the deficiencies in the prior art, makes continuously depoling of rubber hose, enhances productivity, and stops simultaneously potential safety hazard.
The present invention is achieved through the following technical solutions:
The hard core mandrel string of rubber hose of the present invention, its special character is: comprise hauling machine and depoling instrument, the conduction chain of two levels is installed on the base of hauling machine, the depoling instrument comprises baffle plate, depoling die sleeve and drawing bar, baffle plate is installed on the base near the conduction chain porch, the depoling die sleeve is installed on the baffle plate, and depoling die sleeve band is useful on the centre bore that inserts hard core and block flexible pipe, and the end that can be clamped in the drawing bar between the conduction chain connects hard core top.
Preferred version is, described drawing bar connects hard core by connecting rod, the external diameter of drawing bar is identical with hard core external diameter, and the drawing bar end is drilled with core front end firmly that specification is identical, the internal thread hole of opposite direction, and two of connecting rod has processed the external screw thread of lucky connection drawing bar and the hard core of steel.
With the stair coaxial circular hole that is convex, the center, hole is consistent with the clamping center of two conduction chains on the described baffle plate; Depoling die sleeve profile is " protruding " shape corresponding with baffle plate convex-shaped hole.
Described depoling die sleeve is several, and the center hole size difference of each depoling die sleeve is to adapt to the different hard core choice for use of thickness.
The hard core depoling method of rubber hose, first the hose end before the depoling is carried out ring cutting processing, make hard core expose one section of flexible pipe, select the suitable depoling die sleeve of centre bore to be installed on the baffle plate of mandrel string conduction chain porch, the hard core that will expose passes depoling die sleeve centre bore, drawing bar is connected with hard core by connecting rod, then starts mandrel string and carry out depoling; The drawing bar that mandrel string relies on the rubber press on conduction chain and the conduction chain that depoling is used clamps, conduction chain running drive drawing bar moves forward the hard core of drive and goes ahead, the flexible pipe that is coated on the hard core is subjected to baffle plate and the restriction of depoling die sleeve to keep original position, has realized the extraction of hard core.
The invention has the beneficial effects as follows, esy to use, safe and reliable, make continuously depoling of rubber hose, enhance productivity, stop simultaneously potential safety hazard, produce space hold less.

Fig. 1 is structural representation of the present invention, and Fig. 2, Fig. 3 are front view and the top view schematic diagram of baffle plate, and Fig. 4, Fig. 5 are front view and the top view schematic diagram of depoling die sleeve.
Among the figure, 1 drawing bar, 2 clamp briquetting, 3 connecting rods, the hard core of 4 steel, 5 depoling baffle plates, 6 depoling die sleeves, 7 bodys, 8 mandrel string bases, 9 depoling chopping boards.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.
The hard core mandrel string of rubber hose of the present invention, comprise hauling machine and depoling instrument, the conduction chain of two levels is installed on the base of hauling machine, the depoling instrument comprises baffle plate, depoling die sleeve and drawing bar, baffle plate is installed on the base near the conduction chain porch, the depoling die sleeve is installed on the baffle plate, and depoling die sleeve band is useful on the centre bore that inserts hard core and block flexible pipe, and the end that can be clamped in the drawing bar between the conduction chain connects hard core top.Described depoling die sleeve is several, and the center hole size difference of each depoling die sleeve is to adapt to the different hard core choice for use of thickness.
Mandrel string is to realize in the normal traction machine transformation with the horizontally tracting chain, fix baffle plate about a thickness 100mm at the base of hauling machine entrance, the stair coaxial circular hole that is respectively 150mm, 100mm with diameter on the baffle plate is " protruding " shape, and the center, hole is consistent with the clamping center of two conduction chains.
" protruding " shape hole corresponding " protruding " shape steel plate on depoling die sleeve and the baffle plate, external diameter is respectively 99mm, 149mm, and there is the centre bore than the large 0.5-0.7mm of the hard core external diameter of steel in mold center.
Described drawing bar connects hard core by connecting rod.The external diameter of drawing bar is identical with the hard core external diameter of steel, and the drawing bar end is drilled with the hard core front end of steel that specification is identical, the internal thread hole of opposite direction.Two of connecting rod has processed the external screw thread of lucky connection drawing bar and the hard core of steel.
Depoling method is, first the sebific duct hose end before the depoling is carried out ring cutting processing, make the hard core of steel expose sebific duct 10-15cm, select the suitable depoling die sleeve of centre bore to be installed on the baffle plate (being positioned at the mandrel string afterbody) of mandrel string conduction chain porch, the hard core that will expose passes depoling die sleeve centre bore, drawing bar is connected by the hard plug of connecting rod and steel, then starts mandrel string and carry out depoling; The drawing bar that mandrel string relies on the traction of the rubber press on forward part conduction chain and the conduction chain that depoling is used clamps, conduction chain clamping drawing bar moves forward the hard core of drive steel and goes ahead, the sebific duct that is coated on the hard core of steel is subjected to baffle plate and the restriction of depoling die sleeve to keep original position, has realized the extraction of hard steel core.After the steel core of first sebific duct is extracted out, repeat the continuous depoling that above operation realizes sebific duct.
